Another car for MetroMPG: convertible 1991 Pontiac Firefly (Geo Metro)
---
First two efficiency mods of 2010 to the ForkenSwift happened this week, courtesy of the
Firefly convertible project (which itself is sitting patiently, gathering dust in the garage).
Included in that project was a set of four 155/80/13 tires on rims. Ugly, rusty rims. Old tires.
They've been on the ForkenSwift 3 days now, and it's easy to tell that they roll much,
much better than the snows that have been on the car since day one. Not surprising, really:
I already knew the snows were bad. And the rubber on these 155's is probably rock hard! (Not to mention weatherchecked enough that I turned away as I was airing them up to ... somewhere north of the max sidewall figure. Just in case.)
Then I stole the relatively smooth wheel covers from the 'vert and stuck them on the ForkenSwift too, to hide the rusty rims. And improve aero.
